Abstract: Provided is a barrier film comprising a base layer, and an inorganic layer including Si, N, and O, and including a first region and a second region, which have different elemental contents (atomic %) of Si, N, and O from each other as measured by XPS, wherein the film has a water vapor transmission rate of 5.0×10?4 g/m2·day or less as measured under conditions of a temperature of 38° C. and 100% relative humidity after being stored at 85° C. and 85% relative humidity conditions for 250 hours, or wherein the inorganic layer has a compactness expressed through an etching rate of 0.17 nm/s in the thickness direction for an Ar ion etching condition to etch Ta2O5 at a rate of 0.09 nm/s. The barrier film has excellent barrier properties and optical properties and can be used for electronic products that are sensitive to moisture and the like.

Abstract: Example embodiments are directed to an electronic device and a method for manufacturing the same. The electronic device includes a polymer thin film and an electrode. The polymer thin film includes nanoparticles. The electrode is formed by attaching a graphene thin film of a sheet shape formed through graphene deposition using a vapor carbon supply source to the polymer thin film. In the method, a graphene thin film of a sheet shape is formed through graphene deposition using a vapor carbon supply source. A polymer solution with distributed nanoparticles is prepared. The polymer solution with distributed nanoparticles is spin-coated on a substrate. A polymer thin film comprising the nanoparticles is formed by drying the spin-coated polymer solution. An electrode is formed by attaching the graphene thin film onto the polymer thin film.

Abstract: Provided are a photodetector (PD) using a graphene thin film and nanoparticles and a method of fabricating the same. The PD includes a graphene thin film having a sheet shape formed by means of a graphene deposition process using a vapor-phase carbon (C) source and a nanoparticle layer formed on the graphene thin film and patterned to define an electrode region of the graphene thin film, the nanoparticle layer being formed of nanoparticles without a matrix material. The PD has a planar structure using the graphene thin film as a channel and an electrode and using nanoparticles as a photovoltaic material (capable of forming electron-hole pairs due to photoelectron-motive force caused by ultraviolet (UV) light). Since the PD has a very simple structure, the PD may be fabricated at low cost with high productivity. Also, the PD includes the graphene thin film to reduce power consumption.
